rubies-fish
A multi-version Ruby manager for the fish shell.
Features
Switches between Ruby versions by munging PATH, thus avoiding
wrapper-scripts ('shims') for great speed.
Utilizes fish's 'universal' variables to switch versions in all
open shells.
Override chosen version by setting RUBY_VERSION or by having a
.ruby-version file in the current working directory.
Using
Clone the repository somewhere nice, and add the following line to
your config.fish:
. /path/to/rubies-fish/rubies.fish
Then use rubies-select to see all available versions.
Select a global Ruby to use for all shells by running
rubies-select -g <version>.
You can also run rubies-select <version> to select a version
specific to the current shell. Specify global as the version
to go back to the global Ruby version. The same effect can be
achieved by setting the environment variable RUBY_VERSION.
Installing Rubies
rubies-fish does not support installing Ruby. I suggest using
ruby-build.
rubies-fish looks in ~/.rubies by default, but you can change
the directory by setting the universal variable rubies-directory
to something else - eg. add the following line to your config.fish
to share Rubies with rbenv:
set -U rubies_directory ~/.rbenv/versions
